The victim, who was in his 40s, was originally from Lithuania, but had been living in Ireland for four years.

Gardaí are trying to contact his family and will not release his name until relatives have been informed.

Detectives have appealed for information in relation to two crime scenes - one at the beach in Mornington where the body was found, and a site in Drogheda where it is suspected a violent assault could have taken place.
